To @ZZ whom it may concern,.-

Be it known that I, CARL BERNREUTHER, a subject of the Emperor of Germany, residing at Berlin, Germany, have invented certain new and useful Improvements in Apparatus for Providing Oasks or Barrels with Pitch and Removing Old Pitch, of which the following is a specification.

In carrying out my invention hot pitch is used for pitching the cask or barrel anew, as well as for removing the old pitch, and is injected into the cask or barrel by means of an injector, a pump, or other suitable pressurel apparatus through a pipe terminated by a nozzle and inserted in 'the bung hole of the said cask or barrel. For the purpose of removing the old pitch, the injected hot pitch acts as a solvent for the old dirty/pitch still adhering 'to the inner walls of the vessel. Both kinds of pitch thus associated are transferred to a boiler to be reheated, and again injected, this mode of proceeding being repeated as often as necessary.

The apparatus used to carry this process into practice is represented in the accompanying drawings, under various forms.

Figure 1, is a cross section; Fig. 2 another cross section of a modification of the apparatus. Figs. 3 and t show in longitudinal and c ross section the arrangement of my transportable boiler. Fig. 5 shows a modification in which a valve is arranged to be operated by the weight of the cask or barrel when it is placed over the nozzle. Fig. 6 shows a moditied arrangement of the valve of Fig. 5.

a, (Fig. l) is a stationary boiler heated from below. In this boiler is placed the pitch requiring to be heated, as well as a pump, or other pressure apparatus, from which issues a pipe c', extending along theA bottom of the boiler and bent upwardly at right angles terminating with a nozzle o. The upright part of the tube c is surrounded by a casing e, perforated at its lower part, and carrying at k a movable pipe d adapted to be turned by reason of its swivel connection with the casing e, and terminating with a funnel shaped end d, for supporting the cask or barrel.

The heated pitch placed in the boiler passes through the perforations f of the casing e, and through a small hole f, formed in the pipe c,in order4 to arrive below the piston whence it is ejected by a sharp down stroke of the head, g, of the piston, through the nozzle, c, into the cask or barrel. The pitch running 5 5 back out of the cask is caught bythe funnel d, and is returned to the boiler. Any pitch remaining in the pipe c runs oit through the small hole f.

In the arrangement shown in Fig. 2, the in- 6o jection of the pitch results from the depression of the cask oribarrel. For this purpose, the pipe d4 carrying the barrel, and provided with the funnel d5, is firmly connected with a piston Z912, and acts thus as a pressure apparatus. The vpiston blz slides in the pipe b provided at the bottom with openings b2 for the admission of the pitch from the receptacle 0.6. A spring z', constantly presses against the piston Z212, and tends to move it up. The in- 7o jection pipe c2 having the nozzle c3, passes through the piston, and is tightly fixed thereto.

The pitch from the receptacle a6, enters the pipe b', and ascends along the latter through the injection pipe c2, until it reaches the level of the pitch placed in the receptacle 0.6. When the cask is now suddenly pressed down, the pitch is forced from the pipe b', and injected through the nozzle c3, into the barrel. The superfluous pitch passes through perforations 8o in the pipe d4,'above the piston Z212, and may beconveyed to the receptacle a, when the piston is raised.

Figs. 3 and 4 show a modification of the above described invention having the form of 8 5 a transportable boiler a7, provided with an outer casing m. In the-front of the latter is placed the furnace a', and at the rear end, the chimney flue a2, into which` leads a branch pipe 0.3, leading the steam from the boiler to 9o the said fine. The hot gases pass below and along the sides of the boiler and heat the pitch which is conveyed from the pump Z913, along the conduit pipe c4 and injected into the barrel through the nozzle c5, the pipe c4 being 95 fixed to or cast integrally with the funnel d6, while the nozzle c5 is screwed in the pipe c4.

Fig. 5 indicates a valve device which does not allow the pitch to enter the barrel until the latter is tilted over the nozzle. purpose, the barrel rests upon a ring 1 forming one end of a double armed lever 3, ful- For this roo crumed at 2, the other end of which carries a counter Weight et. In the outlet of the piston cylinder bx, is arranged a valve 5, connected by a lever arrangement 6, with the lever 3. lVhen the Cask or barrel is tilted over the nozzle, and rested upon the funnel d, the ring 1, is pressed down, the counter weight is raised,and the valve 5, also from its seat. In this manner, the outlet opening of the pump is released, and the pitch can be injected in the cask or barrel. As soon however as the cask or barrel is removed the counter-Weight 4, sinks and closes by the aid of the valve 5, the outlet or opening.

Fig. 6, shows an intermediate piece inserted in the conduit pipe and provided with a valve, this arrangement having for its object to allow, when the apparatus is not in use (and hence when the valve is closed) the pitch still remaining in the pump to run 01T through a small opening flo in the bottom of the pump cylinder and back into the receptacle.

It will be understood that the valve of Figs. 5 and 6 may be used with all the forms of apparatus shown in the other figures including Fig. 2.

I claiml. In combination, the pitch tank, the i11- jection pipe having a nozzle, the pressure forcing device and the funnel d surrounding the injection pipe, substantially as described.

2. In combination, the pitch tank, the injection pipe and nozzle, the pressure forcing device the valve the ring l arranged to be operated by the barrel when placed over the injection pipe, and the connection therefrom to the valve substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name in pres ence of two subscribing Witnesses.
